- This invention relates to machines for printing addresses or othermatter on periodical publications or the like and the salient object isto provide a novel automatic machine wherein a series of printingdevices bearing address forms may be successively moved into printingposition and wherein the periodicalsor the like may be successively fedinto printing position'whereby an address may be printed upon eachperiodical.

Other objects are to feed the individual printing devices intoprinting'position and to automatically determine whether or not aprinting device isto be printed so that impressions may be made fromsome of the printing devices while others will be as it is termedskipped; to interrupt the feed for the periodicals when a' printingdevice is to be skipped; and to retain a printing device from which animpression is to be made in-printing position in the event no periodicalis fed.

* Heretofore periodicals have usually been fed into machines of thecharacter to which this invention appertains by hand or they have beenfed into the machine'automatically from a stack disposed adjacent thereceiving endof the machine. 'Ihehand operation is expensive andrequires one or more operators. The automatic stack feed time operationdoes'not always prove satisfactory in that more than one periodical issometimes fed into the machine thereby preventingproper operation; Itistherefore a. still further object to provide a novel feedingmechanismwhich will automatically feed only one periodical at a time into themachine and which will be positive and constant in operation.

Still further objects are to provide intermittently operating travelingchains for feeding the periodicals to the machine, to feed theperiodicals I into printing position in. the machine after move I Fig. 3is a longitudinal sectional view taken,

In the accompanying drawings, 1 is a suitable frame in which a driveshaft 2 is journaled-having a flywheel 3 on one end thereof driven bysuitable means such as an electric motor (not shown). A handle 4 may beprovided on the'flywheel for operating the machineby hand when sodesired. A collar 5 rotates with the shaft and is rigidly mounted on'the shaft 2 adjacent the flywheel. A pawl 6 on the collar is arrangedadjacent the flywheel and is adapted to engage a slot in the shaft 2.The pawl 6 operates with the arm 8 (Fig. 4) which forces it into or outof the slot, a spring 9 normally holding the pawl inwardly. Thismechanism forms the main clutch 10 that is clearly illustrated in Fig.4. A gear 11 on the shaft 2 meshes with a gear 12v on the cam shaft 13to operate the mechanism for feeding periodicals one at a time into themachine. The cam shaft 13 extends transversely across the machine andthe ends thereof are mounted in suitable journals 14 and 15 in the feedmechanism casing 16. On the cam shaft 13 is a main gear 17 that drives agear 18 (Fig. 1) mounted'on the shaft 19 of the belt conveyor throughthe idlers 20 and 20 (Fig. 1) journaled in the side of the casing 16;The wide idler gear 21 (Fig. 5) mounted on the stub shaft 23 is meshedwith both gears 1'7 and 22. The gear 22 is fast on the shaft 26. Pulleys2'7 spaced on shaft 26 are free to rotate with the shaft. Spaced fromshaft 26 is a shaft 28 carrying pulleys 29. A pair of belts 30, 30' aredirected about these pulleys as shown in Fig. 2. The pulleys arepositioned and are of suflicient diameter to allow the bottom, edges ofthe belt to just clear the top of the machine and render suflicientfriction to al- 7 low the articleto be printed to be carriedlongitudinally across the machine. As shown in Figs. 1 and 2, the shaft28 is supported by uprights 31 mounted on the frame and these uprightshave their bases groovedat 32 to permit longitudinal adjustment thereof.A gripper roll'rocker 35 is mounted on shaft 34 (Fig. 5) supported by ahanger 33 connected to the casing 16 and extending downwardly therefrom.A pair of juxtaposed arms 36 rigidly formed on the rocker 35 carry ashaft 37. A lever 38 is pivotally mounted on this shaft and carries aroller 39 riding on a cam 40 fixed to shaft 13. A spring 41 attached tothe upper end of 'lever 38 holds roller 39 against cam 40 and rotationof the cam moves lever 39 rectilinearly, which motion is transmitted togripper roll rocker 35. Arms 42 on rocker 35 support a shaft 43 on whichthe gripper rolls 46 are mounted. A shaft 47 mounted in the framecarries agear 48 driven from the main gear 17 through idler gears and45' (Fig. 1). Feed rollers 50 are fast on shaft 47 opposite the grippingrollers 46. The rollers 46 and 50 are driven to rotate in oppositedirections so that when the gripper roll rocker reciprocates toward thefeed roller shaft 47 the article to be printed is grasped or clampedbetween the rollers and fed into the machine. In order to providepositive feeding of the periodical or other article to be printed, apneumatically operated feed is provided comprising a rockable hollow rodor sucker bar 51 having one end pivotally connected to a valve casingand the other end connected to the side of casing 16 by an arm 53 thatis free'to travel in a slot 54 in'the casing (Fig. 1). Means (such as anair compressor which is not shown) are provided for creating a vacuum inthe sucker 1 bar. On the stud 5 5 (Fig. 3) extending inwardly fromcasing 16 are two levers 56 and 57. The sucker bar. 51 has open ends 51movable between the shafts 43 and 47 to engage forward marginal edgeportions of the bottom periodical of the stack to pull it downwardly andpartly around the feed roller so that the gripper roller may clamp thisbottom-periodical against the feed rollerto withdraw. the bottomperiodical from the stack. While the sucker bar is thus operating thefingers 65, to be described, are sunk away from the stack and after thesucker bar has pulled the front portion of the periodical downwardlythefingers again engage the stack to prevent other periodicals frombeing affected while the magazine is being fed away. A pneumatic valve66 (Fig. 3) in the valve casing is timed to create suction when the feedroller moves toward the periodicals and upon reverse movement this valveshuts off the sucking action and releases the grip on the periodical atapproximately the same time the. rollers 46 and 50 engage the pe-'riodical to carry it on into printing position. The

periodicals are arranged at the right hand end of the machine as viewedin Fig. 1. To feed the periodicals a chain feed shaft 153 (Fig. 10) isjuxtaposed to the feed roller shaft and carries a* plurality ofsprockets 154 and is rotated by a ratchet-155 fixed to one end thereof.Endless chains 156 arearranged on these sprockets and connect the chainfeed shaft with another shaft (not shown) to move the chain along thetable 157 to carry periodicals stacked thereon to feeding position. Abell crank 158 is loosely mounted on the chain feed shaft 153 andcarries mechanism to rotate this shaft. One arm (Fig. 11) of the bellcrank has a stud 160 fixed thereto to which one end of a link 161 ispivotally connected.

The other end of this link is pivotally connected to a stud 162 fastenedto the gear 12. A pawl 163 is pivotally connected to the arm 164 of thebell crank for operating the ratchet. A spring 165 has one end connectedto the pawl and the other connected to a lug 166 on the bell crank fornormally holding the pawl against the ratchet. The cam shaft 13 has acam 167 rigidly fastened thereto which operates against a roller 168mounted on a cam lever 169 to reciprocate the cam lever. The upper endof the cam lever is pivotally connected to the feed control rocker 170and reciprocates the same. A spring 171 normally holds the cam lever inoperative posi tion against the cam. The feed control rocker 170 (Figs.11, 12 and 13) has downwardly disposed feed control fingers rigidlyconnected thereto and against which a periodical strikes as it is beingfed into the machine. Pressure against these fingers causes movement ofthe feed control rocker which is transmitted to the cam lever 169. Whenthe feed control rocker is moved inwardly, the roller 168 is moved ashort distance away from the cam 167 so that the cam only works on theroller at certain points and gauges the distance the arm 173 is totravel in operating the pawl 163. When the feed control fingers aremoved inwardly substantially the full distance of this inward travel,the roller 168 is entirely removed from the cam 167 and when no movementis transmitted to the arm 173, the pawl is held away from the ratchet.To prevent a periodical from pushing the feed control fingers too farinwardly and prevent action of the pawl on the ratchet, a plurality ofdownwardly disposed stop fingers 145 are fixed on the frame in front ofthe feeding end of the machine to limit this feed of the periodical sothat the pawl may be free to work the ratchet thus assuring proper feedof periodicals into the machine. When the periodicals are fed staggardlyinto the machine and while the feed control rocker reciprocates, thefeed control fingers determine the movement of the arm 173 whichcontrols the movement of the chain feed shaft for gauging the propermovement of the chains so that the periodicals will be continuously andproperly fed into themachine. The sucker bar is timed so that on itsforward movement there is a suction-in the bar for assisting in pullingthe periodical into the machine and then release the periodical at theproper time by shutting off the suction. The lowermost periodicalsshould normally abut against the stationary stop fingers 145. If thelowermost periodicals do not abut against the fingers the oscillatingfeed control or feeler fingers 65 will move to the left (Fig. 12) tomake contact with the front edges of the said periodical and the chainwill operate to feed the lowermost periodical to the right (Fig. 12)into contact with the stationary fingers 145. Thus, the bottomperiodical is positioned to be pulled downwardly by the sucker bar, asabove described. In operation periodicals are arranged on the feedchains which travel along the table 157, due to rotation of the chainfeed shaft, and place the periodicals on the feed shelf where they arepropelled inwardly by the feed rollers, it being assumed that a printingdevice has been selected for printing and is in the proper printingposition. The pneumatic suckers then pull the forward end portion of thebottom periodical downwardly between the feed rollers and the gripperrollers. The finger bar rocks forwardly and the finger bar fingersprevent more than one periodical from have gone through one cycle ofoperation and is again ready to feed and print another periodical. If,however, the selector-mechanism, to be de scribed,*is not functioning,or a printing device is not in printing position, or certain printing(18-. vicesnot to. be printed are fedinto the machine, the selectormechanism will operate to shut off the suction in the sucker bar andwill move the I finger bar fingers to obstruct the feeding end a fan,

of the machine so that no periodicals will be fed into the machine. Thebelt conveyor, referred to, comprises shafts 19. and and shafts 71 and72. Rollers 73 over which endless belts 74 are directed are mounted onthese shafts and movement is imparted thereto from the belt roller shaft19, the roller 73 on the shaft 19 being fast thereto while the otherrollers are rotatably mounted on their respective shafts. The belts 74carry the periodical to printing position and after it is printed theycarry it beyond, the machine to a suitable table or receptacle (notshown) Suitable belt tighteners' 75 take up the slack in the belt 74. Alongitudinal cam shaft 76 (Fig. 2) on the rearward side of the framereceives motion from. the drive shaft 2 through bevel gears '77 and 78.The platen 82 (Fig. 9) iscarried by a platen arm shaft 83 mounted in theframe of. the machine and is operable by cams provided on the shaft 76,this arrangement being shown in Letters Patent No. 1,481,860, patentedJanuary 29, 1924. A printing device magazine 85 is arranged at the rearof the machine medially thereof into which printing devices areintroduced'which'are withdrawn therefrom and fed into printing positionby intermittently oper-. atedfeed chains 87 which move a printing devicethrough selecting position before moving it into printing position. Thefeed chains are arranged in parallel relation and are directedaboutsheaves 90. and about sprockets 91 to be driven'thereby.

' The. sprockets are fixed toa shaft 92 (Fig. 6) and one of thesprockets has a number of projecting pins 93 -thereon. A pawl 94 carriedby an arm 95 successively engages these pins to turn the sprockets andthereby impart a step-by-step movement tothe chains. The arm 95 is partof a rocker 96 and is actuated through suitable connections by cams onshaft 76. (See Fig; 9.) After the printing devices have been. movedthrough printing position they are engaged by a suitable packer rocker102 (Fig. 1) so timed and constructed that as soon as the printingdevice 7 falls into a storage drawer supported below the printingdeviceguideway, the packer urges the device and the preceding devicesrearwardly in thev drawer to permit the passage of succeeding carries anupwardly extending arm 105' having a cam roller 106 thereon (Figs. 1aand 2). This roller rides on a cam 107 fast on driving shaft 2. One endof a spring 105" is fastened to bar 105 and the other end is fast to theframe to thereby hold roller 106 against cam 107. The forward end of bar105 carries a clutch member 108 (Fig. 1) engageable with a clutch member109 (Fig. 1) fast on the rod 110 communicating with clutch 10 onflywheel 3. When the clutch members are engaged as shown in Fig- 3 themachine is in operating position, but when disengaged the pawl 6 is heldfrom engagement with the flywheel and therefore the machine isinoperative. When the roller 106 rides onto the low portion of cam 107it moves bar 105 outwardly and also moves the clutch members 108 and 109out of engagement, thereby lifting the rod 110 and disengaging theclutch 10. The arm 8 disengages the pawl 6 from the slot in the driveshaft 2 thereby interrupting operation of the machine and the driveshaft will operate idly. However, this condition is only desired when noprinting device is to be fed. Therefore means are provided to hold theclutches in engagement when the printing device is operating properly. Arod 111 (Fig. 1) connects bar 105 to pivoted finger 112 (Fig. 9)arranged on the periodical rack. When the printing devices are arrangedin the magazine, the finger 112 acts through rod 111 to move bar 105outwardly, thereby holding the cam roller 106 from movement into the lowspot of cam 107 and thus the clutch members 108 and 109 are held inengagement with each other. When there are no printing devices in themagaine the roller will move onto this low spot to disengage the clutchmembers and interrupt operation of the machine. When a printingoperation is being performed the periodical or other article beingprinted is held against movement and this is attained by providing stops113 and 114 (Fig. 1) to hold the periodical against movement with thebelt during a printing operation. The stop 114 holds the periodicalbeing printed against movement and the stop 113 prevents the succeedingperiodical from being fed against or on top of the one being printed.Each stop comprises fingers 115 projecting from a bar 116 rigidlyconnected to a rod 117 supported in suitable bearings 118 carried by theframe and is provided with arms 119 (Fig. 3) supporting rollers 119which lightly rest on the article to insure movement thereof with thebelt. An arm 121 (Fig. 5) secured to the end of the bar 116 carries aroller 122 that is loosely mounted thereon. This roller rides on a cam123 fast on longitudinal shaft 124 driven from shaft 19 through gears125 and 126. When the rollers 122 ride onto the low portion of the camsthe stops 113 and 114 fall downwardly by their own Weight. When therollers move onto the high portion of the cams the stops are raised andwhen in this position the periodicals are free to be moved by the belt74. The selecting mechanism of this machine operates in the mannerdescribed in the patents previously referred to, to determine or selectsome printing devices to be printed while others are, as it is termed,skipped. When a printing device is skipped a periodical is not fed intoprinting position and thus the periodicals are prevented from passingthrough the machine without receiving a printing impression.Furthermore, means are provided whereby the failure of a periodical tofeed into printing position will prevent the discharge of a printingdevice from printing position that has been determined to be printeduntil a periodical moves into printing position. A rod 127 (Fig. 6) isconnected at one end to an arm 127'" on a rod 127 which extendstransversely in the frame. The other end of the rod 127 is connected toan angle lever 227 pivoted at 227 on the frame and adapted to engage apin 227" on pawl 94 for releasing the pawl from pin 93 on sprocket 91. Aspring 128' attached to the arm 127 and to the frame normally holdsthese parts in position with the pawl 94 out of operative relation tothe pins 93 on the sprocket; but when a periodical is fed to printingposition it will depress a roller 129, which is mounted on the arm 128and projects up through an opening 130 in the table 130 of the machine,and the rod 127 is thus shifted to the right (Fig. 6) and the pawl 94 isthen permitted by the angle lever 227 to engage one of the pins 93 foroperating the printing device feed. In the absence of a periodical fordepressing the roller 129, the feed pawl 94 will be held in inoperativeposition so that the printing device feed will not operate and this isdesirable because a printing device to be printed should not bedischarged from print ing positionuntil an impression has been takentherefrom. For insuring proper engagement of the periodical with therelease roller 129 a double roller 134, carried by a rod 133 on asupport 132 on the. frame, is arranged over the opening 130 in thetable. When'there is no periodical present under the rollers 134 therelease roller 129 will be projected by the spring 123' through theopening 130 in the table and between the rollers 134, as shown in brokenlines in Fig. 6, and the feed pawl 94 will then be in inoperativeposition; but when a periodical is fed beneath the rollers it will forcethe release roller down against the tension of its spring 128 and causethe printing device feed to operate. A handle arm 131 is connected tothe arm 127', which is in the form of a casting mounted on the rod 127and forming a support for the arm 128 so that the printing device feedcontrol may be operated manually when desired. This handle alsofunctions as a counterweight to supplement the spring 128'. The handlearm 131 has a roller 135 thereon which rides on a cam 136 fastened onshaft 124. When the roller rides onto the low portion, of the cam 136the wheel 129 is free to rise through the slot 130 and when the rolleris ona high portion of the cam the wheel 129 is held downwardly. Thisarrangement permits a printing device to pass to printing position whereit is retained for a printing operation. A bar 137 at the left hand endof the machine (Fig. 2) is similar to the stops 113 and 114. This barserves to retard the movement of the periodical onto the receiving tableand afford sufficient pressure to allow the periodical to be propelledby the belts 74. To prevent a periodical from being fed to printingposition when a printing device is to be skipped a yoke 138 (Fig. 11) ispivoted to the frame and is operated by a rod 139 connected withselector pin bar 104. When the selector pin bar is operated by aprinting device to be skipped, the yoke 138 is reciprocated. A bellcrank 139 pivotally mounted on the frame carries a roller 140 whichcontacts with an edge of the frame and during reciprocation of the yokethis bell crank is moved. An arm 141 of the bell crank is connected to arod 142 communicating with the arm of the pneumatic valve 66. Movementof the arm 141 causes rod 142 to move longitudinally and preventsreciprocation of the arm 69 thereby shutting off suction in the bar 51to prevent the bar from drawing a periodical into the machine. A rod 143is connected to the arm 141 and is operated in the same manner as rod142 and prevents reciprocation of the finger bar170. When the finger baris stopped it will be in the position shown in Fig. 3 and periodicalswill be prevented from feeding. The periodicals travel in suitableguides fastened to the top of the frame to assure proper positioningthereof relative to the platen and also to assure proper orientationduring a printing operation.
